The power source, eg generator, gives out both power and a default signal.
The Not gate passes the power and the inverted signal along. It does not use power to infer a signal state, nor create infinite power.
Doors etc uses the signal to decide whether to turn on or off.
So no infinite power.

Having said all of that I would much rather just have the doors, draw-bridges, etc have an option to change their default state.
I'm trying to follow this concept...
So when I have [[ Generator ]] --> [[ Switch ]] --> [[ Lightbulb ]] is the current or the signal interrupted by the switch? My answer is
both because they are intermingled. The power
IS the signal.
But you are saying that a wire passes both the power and the state information separately...
[[ Generator ]] --> [[ Switch(on) ]] --> [[NOT]] --> [[ Lightbulb ]] would not allow the power to continue to flow but invert the "signal" to Off... Thus a bulb that consumes power but no light.
however, NOT gates work both ways, so
[[ Generator ]] --> [[ Switch(off) ]] --> [[NOT]] --> [[ Lightbulb ]] would allow the power to continue, but invert the "signal" to On?... Thus a bulb that creates light but consumes no power.
If Neither of these examples work at all then you have effectively no reason to have a NOT gate at all. If you are focusing more on doors, etc., that really require no power to change state in their most basic form, then I can see that all you really need is a power BUMP to change states, not continuous voltage, but what if you are using a turret or a blade trap instead of the lightbulb in the examples above? There are
far more possible combinations that are either broken by design, or else would need to be excluded from functioning by TFP for that application.
I get that you are looking at basic game mechanics and going "Well, why not just do it this way?" (or not even looking at the game mechanics at all), but it is coming across as if you think it makes no sense to do any other way ...I'm just saying that it is possible to do in game logic gates that are actually logical and are a lot like actual real life circuit diagrams.
** I'm starting to see why TFP is reluctant to add logic gates.
